The mechanisms of noise generation also result from aerodynamic phenomena, i.e. the air-flow with the accompanying pressure changes around the moveable elements [18]. As in the case of a vehicle tire [19], this type of noise is generated in the belt conveyor by the belt engaged with the idlers and the pulleys .

Air Conveyors. A company quoted £130,000 to reduce noise from air conveyors (airveyors) by installing noise control enclosures. The customer chose our company instead. Our sound solution was very successful, suppressing the noise by 6 dBA and reducing it below the 85 dBA target. Our noise solution cost only £2500, saving £127,500. Air Knife.
